Fitbit estimates sleep stages using a combination of movement and heart-rate patterns. While you’re sleeping, your device tracks the beat-to-beat changes in your heart rate, known as heart rate variability , which fluctuate as you transition between light sleep, deep sleep, and REM sleep stages. Sleep stages are traditionally measured in a lab using an electroencephalogram to detect brain activity along with other systems to monitor eye and muscle activity. Fitbit’s trackers can’t match this level of medical accuracy but can estimate your sleep stages every night. Apple Sleep uses motion sensors, heartbeat sensors, and microphones to detect micro-movements to track of how deeply users are sleeping.
In addition, the Inspire 2, Charge 4, Versa 3 and Sense all feature Caller ID and Text notifications, buzz and show on screen who’s calling when your phone rings. With watchOS 7 Apple adds a Sleep app to the Series 3, 6 and entry-level SE Watches. It helps you establish a regular bedtime routine and keep track of your sleep trends night after night. Scientists are increasingly linking weight gain and poor metabolism to sleep deprivation, so getting a good night’s sleep should be part of your health, fitness and weight-loss strategy. Sleep loss can lead to an increased prevalence of diabetes and obesity. We should all be aiming for 8 hours of sleep per day.

With the Watch, you can also create an album of photos stored on your watch and share these with people. You can also create a Watch face with one of your photos as the background. Fitbit also goes into much greater detail on the different Sleep Stages you go through, and now offers a nightly Sleep Score on the quality of your sleep. But that is not as impressive as Fitbit battery life that can last a week or more between charges.
